Cabling to mains water feature pump

[geezza]

Hi All,

Been asked to connect up a mains water feature which comes with a 10m rubber flex.
Just wondering if anyone else has done this and how they protected the cable to the pump from mechanical damage.

Thanks
Geezza

you could put it in copex ( all plastic to avoid metallic corrosion ). most don't bother unless there's danger of mechanical damage. nott good in a pirhana pool.

Is it ok the bury in the ground and give enough mechanical protection.

Do you mean this?

if buried, yes, but bear in mind the steel will corrode fairly quickly unless it's stainless. pvc tube with a bend or 3 is also an option.

Doesn't the PVC protect the steel... Isn't that the idea?

But PVC won't provide any mechanical protection

Good point, so you think this https://www.tlc-direct.co.uk/Products/BHSP20B.html
will provide enough protection, both mechanical and against corrosion

true, but in our climate, eventually it will rust. damp gets inside the copex. same with a IP66 box i have outside. the steel nut on the inside of the SWA gland is rusted on solid after only 5 years outside.

Whats the alternative, that will provide mechanical and corrosion protection then

I'm on the Industrial side mate. That is why I asked the question. The domestic guys will know how good this stuff is for gardens.

that will be as good as you'll get without spending a fortune. all depends on where the cable is buried. under slabs youonly need pvc, but where digging is possible, reinforced containment with warning tape 6" above is preferrable.

Cheers telectrix,
Think I'll have to go with the flexible steel conduit and warning tape

Have the connection between the SWA and the pump "cable" above ground, in something like a Wiska box.

i have a similar set-up. IP rated ad. box. T/E directly in through wall. SWA out to shed, 2 flexes (under slabs in 20mm pvc) out, 1 to pump, other to lamp post. remote receiver inside ad. box. handset inside house. why get wet when i want them switched on?
